COMPLETE ASSIGNMENT OF THE H-1-NMR AND C-13-NMR SPECTRA OF [1]BENZOTHIENO[2,3-C]NAPHTHO[1,2-H]QUINOLINE AND ,3-C]NAPHTHO[1,2-H][1,2,4]TRIAZOLO[4,3-A]QUINOLINE - CONCERTED USE OF 2-DIMENSIONAL NMR TECHNIQUES

The H-1- and C-13-nmr spectra of [I]benzothieno[2,3-c]naphtho[1,2-h]qu inoline and 3-c]-naphtho[1,2-h][1,2,4]triazolo[4,3-a]quinoline were to tally assigned using a combination of two-dimensional nmr techniques. After correlation of the proton signals by a COSY spectrum and one-bon d heteronuclear correlation, complete assignment of the H-1- and C-13- nmr spectra of the novel heterocyclic compounds required the applicati on of long-range CH coupling information particularly for quarternary resonance assignment and the orientations of individual spin systems r elative to one another.
